We look at the division of 66795415 by 775 
We want to divide 66795415 by 775.

Moving on to step 1:
775 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 775

Moving on to step 2:
When dividing 66 by 775, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (7) from the dividend, add it to 66, then carry on: 667 / 775

Let's proceed to step 3:
The number 775 fits into 667 0 times, leaving a remainder of 667.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 667 after subtracting 0 from 667.
Fetch the next digit (9) from the dividend, attach it to 667 and continue: 6679 / 775

Going ahead to step 4:
775 goes into 6679 8 times with a remainder of 479.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6200 from 6679 to get 479.
Take the next digit (5) from the dividend and append it to 479, then repeat: 4795 / 775

Step 5:
If we divide 4795 by 775, we get 6 and a remainder of 145.
The next digit of our result is 6. 
Result so far: 86.0
The remainder is 145 after subtracting 4650 from 4795.
Bring next digit (4) of the dividend behind the 145 and repeat the process: 1454 / 775

Let's proceed to step 6:
The number 775 fits into 1454 1 times, leaving a remainder of 679.
Write down 1 as next digit of the result. 
Result so far: 861.0
Deduct 775 from 1454 and we're left with 679.
Include the next digit (1) from the dividend after 679, then repeat: 6791 / 775

On to step 7:
If we divide 6791 by 775, we get 8 and a remainder of 591.
Write down 8 as next digit of the result. 
Result so far: 8618.0
Deduct 6200 from 6791 and we're left with 591.
Append the next digit (5) from the dividend to 591 and continue with: 5915 / 775

Advancing to step 8:
5915 divided by 775 is 7 with a remainder of 490.
Write down 7 as next digit of the result. 
Result so far: 86187.0
The remainder is 490 after subtracting 5425 from 5915.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 9:
775 can be fit into 4900 6 times, resulting in a remainder of 250.
Use 6 as the next digit of our solution. 
Result so far: 86187.6
Subtract 4650 from 4900 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 10:
If we divide 2500 by 775, we get 3 and a remainder of 175.
Record the quotient 3 as the next digit in the result. 
Result so far: 86187.63
Subtract 2325 from 2500 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 11:
When dividing 1750 by 775, we get 2 with a remainder of 200.
The number 2 becomes the next digit in our result. 
Result so far: 86187.632
Subtracting 1550 from 1750 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
775 goes into 2000 2 times with a remainder of 450.
Put 2 as the next digit of the answer. 
Result so far: 86187.6322
Subtracting 1550 from 2000 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

The final result is 86187.6322 with a remainder of 0.0045.
